Abstract: PURPOSE:To accurately achieve positioning by forming a cut-out which is larger than a target mark at an inner-layer copper-clad lamination plate directly below the target mark, laminating an outer-layer lamination plate as a multilayer lamination plate, and then performing copper-plating to an outer-layer circuit pattern and the target mark. CONSTITUTION:An inner-layer copper-clad lamination plate 56 and an outer-layer lamination plate 50 are formed by laminating copper foils 60 and 54 on one surface of semi-transparent insulation substrates 58 and 52. A circuit pattern 62 is formed at the inner-layer lamination plate 56 by photoetching. A clearance 66 which is cut larger than a mark 70 is formed on the pattern 62, directly below a target mark 70 formed at the outer-layer lamination plate 50. A multilayer lamination plate 74 is formed while sandwiching an insulation layer 72 between the inner-layer lamination plate 56 and the outer-layer lamination plate 50. An outer-layer circuit pattern consisting of a land 68A, a target mark 70A, etc., is formed at the multilayer lamination plate 74. Then, a copper-plated layer 76 and a pre-flux layer 78 are formed on the pattern, thus achieving an accurate positioning.

Title: Device for buffering dump body of dump truck
Inventor: NAITOU KANEAKI
IPC: B60P1/16
Filed: 1977-10-28
Abstract: PURPOSE: To easily mount a tilting cylinder at a dump truck by providing a buffer unit operated by the tilting dump body of the truck at the intermediate portion of a pipe for connecting the cylinder to a switching valve for controlling the cylinder.  
     CONSTITUTION: When the dump body 2 of a dump truck is tilted down by turning a control lever 7 to the left, a tilting cylider 4 is communicated with a tank 9. Since the passage in a switching valve 8 is however, throttled, hydraulic pressure is generated in a pipe 6 to retain a valve rod 20 and a valve plate 17 upwardly to thus cause oil in the cylinder 4 to be flown through first and second ports 13, 14 into the tank 9. When the dump body 2 is tilted down to predetermined angle, the valve rod 20 is depressed by a lateral girder 11 to thereby lower the valve plate 17 to break between the first and second ports 13 and 14. Since the oil is flown thereafter through the small hole 18 of the valve plate 17, the dump body 2 is tilted down at slow speed to thus buffer it. Thus, it can separate the buffer unit 10 from the cylinder 4 so as to easily mount the cylinder 4.

Abstract: PURPOSE:To efficiently control data transmission by synchronizing a data transfer request signal in each terminal and transmitting a data transmission request signal to a network terminal terminal equipment from the terminal in case of coincidence between received terminal information and the terminal number of the terminal itself and the presence of transmission information. CONSTITUTION:A data transfer request signal F consists of a synchronizing signal S and terminal numbers 0-3, and terminals T0-T3 synchronize the signal F by the signal S. Terminal numbers 0-3 are transmitted after the signal S. Each of terminals T0-T3 receives this signal to have the right of data transmission if the received terminal number coincides with its own terminal number. When the terminal T0 requests data transfer, it transmits a data transfer request signal R to a network terminal equipment N while the terminal T0 has the right of transmission request and transmits transmission data D simultaneously. The signal R is transmitted continuously till the end of transmission data, and during this period, the equipment N transmits the synchronizing signal S to synchronize the signal F to disable the other terminals to transmit data. After data transmission of the terminal T is terminated, the signal F is restarted with the terminal number of the terminal T1.

Title: Sensor for detecting fluid oscillation generated by fluidic element
Inventor: NAGANO YUICHI
IPC: G01F1/00
Filed: 1992-05-22
Abstract: PURPOSE:To eliminate erroneous accumulation caused by continuous oscillation by providing a decision circuit which interrupts flow rate signal when an output signal from a single phase piezoelectric film has a level deviated from a reference range. CONSTITUTION:A decision circuit 7 receives a decision criterion range defined based on measurements of magnitude range of flow rate signal outputted under steady state. Fluid oscillation in a fluidic element 1 is introduced into a fluid oscillation detecting chamber 3 in a sensor and electric signals of reverse phase are outputted from piezoelectric films 4, 4a. The electric signals are fed to an accumulated flow operating circuit 8 in order to operate flow rate. Signals outputted in phase due to influence of disturbance are not decided 7 as flow rate signals but canceled. When a decision 7 is made that the output signal from the single phase piezoelectric film 4 or 4a has magnitude deviated from the criterion range, flow rate signal is not delivered to the operating circuit 8 but canceled. This sensor prevents erroneous accumulation due to continuous oscillation other than fluid oscillation.
